Privacy rights management in multiparty multilevel DRM system

Abstract

Traditional Digital Rights Management (DRM) systems are one level distributor system which involve single distributor. However, for a flexible and scalable content distribution mechanism, it is necessary to accommodate multiple distributors in DRM model so that different strategies can be implemented in diverse geographical areas. We develop a multiparty multilevel DRM model using facility location and design a prototype DRM system that provides transparent and flexible content distribution mechanism while maintaining the users' privacy along with accountability in the system.
